I'm trying to create a 4D plugin to host ECL (OS X 10.5.8). I call cl_boot when
the plugin is initialized, but 4D always crashes. If I trace under GDB, it
appears to crash in GC_push_all_eager at the line "q = (ptr_t)(*p);"
I have included part of the crash report below. Unfortunately, I know just
enough C to be dangerous so I don't really have a clue on what I might need to
do to fix it. I have messed with the various boot options without success.
Does cl_boot have to be called from a particular thread? If so, how do I
achieve that?
Thanks for any suggestions or ideas.

/* check all pointers in range and push if they appear */
/* to be valid. */
lim = t - 1 /* longword */;
for (p = b; p <= lim; p = (word *)(((ptr_t)p) + ALIGNMENT)) {
q = (ptr_t)(*p);
GC_PUSH_ONE_STACK((ptr_t)q, p);
}
# undef GC_greatest_plausible_heap_addr
